Designations

  • Doctor of Philosophy, Biological Sciences, Simon Fraser University
  • Bachelor of Science, Zoology, University of British Columbia

Research Interests

Avian ecology and wildlife ecotoxicology; effect of pollution stressors (pesticides, endocrine disruptors, industrial and urban pollutants) on insects, birds and aquatic ecosystems; understanding the effects of chemicals on whole life cycles of birds; freshwater ecology and pollution

Current Research

  • Effects of pesticides and land use on farmland and insectivorous birds
  • Understanding fate of neonicotinoid insecticides in wetlands with implications for aquatic insects and birds in agricultural ecosystems, with special interest in the Prairie Pothole Region 
  • Investigating changes in hormone homeostasis in birds exposed to endocrine disruptors and industrial pollutants- effects on learning, cognition and migratory behaviour.
  • Urban stream pollution and river bird health and reproduction
  • Effect of small scale run of the river hydro on river birds and mountain stream ecosystems
